Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of insecticidal compound agent that contains MTI-446 and desinsection list.
Background technology
MTI-446, English common name (dinotefuran), chemical name (RS) 1-methyl-2-nitro-3-(tetrahydrochysene-3-furfuryl) guanidine.Belong to the outstanding kind of third generation nicotinic insecticide, it has larger change with the chemical constitution of existing nicotinic insecticide, has replaced former chloro-pyridine base, chloro thiazolyl with tetrahydrofuran base.This medicament is nAChR antagonist, acts on the cynapse of insect central nervous system, the stomach toxicity of tagging.Can effectively prevent and treat biting mouthparts and sucking pest, and show very high insecticidal activity at very low dosage.It is safer in the use that this medicament is compared second generation nicotinic insecticide, and activity is higher, can be applicable to numerous crops such as paddy rice, sugarcane, vegetables, fruit tree.
Desinsection list, English common name molosultap, chemical name is 2-dimethylamino-1-thiosulfonic acid sodium base-3-thiosulfonic acid base propane, molecular formula is C5H14O7S4Na.Desinsection list belongs to sandworm toxin insecticide, and mechanism of action uniqueness is acetylcholine competitive inhibitor, makes insect nerve not produce reaction to external irritant.Have stronger tag, stomach toxicity and interior suction conduction.The larva of Lepidoptera, homoptera pest is had to good preventive and therapeutic effect, and the low use safety of toxicity.Be mainly used in preventing and treating the insect on the crop such as sugarcane, paddy rice.
But desinsection list mainly exists three shortcomings in actual use, one, owing to having used for many years, has made insect produce serious pesticide resistance; Its two, this medicine has very strong poisoning ability to silkworm, and the longevity of residure is long, so while use in silkworm and mulberry producing region, there is the risk of polluting mulberry leaf and mulberry tool and then poisoning silkworm with poison due to medicament drift; Its three, when this medicine directly sprays some crop such as Chinese cabbage, wild cabbage, because medicament is attached on cauline leaf, can produce harmful effect, in the time that summer high temperature or plant growth are weak, be more subject to especially poisoning.
Different cultivars composition carries out composite, is the very common method of control resistant insect.In most cases, the composite effect of agricultural chemicals is all additive effect, and the composite of part can reach synergistic effect.Completely different to the mechanism of action of target pest from desinsection list based on MTI-446, MTI-446 and desinsection list just can be produced to reasonable synergistic effect after composite, both composite uses also can expand insecticidal spectrum, improve insecticidal effect, reduce dosage, reduce costs, delay generation of pest resistance to insecticide etc.More contribute to bring into play its good effect needs a large amount of experiment and comparative studies but which type of formulation composite rear selection makes.
There is report that MTI-446 and desinsection list are made to spray-type as wetting powder, water dispersible granules or suspending agent etc. after composite, for example Chinese patent application publication number is CN101971856A, has described the application example of its co-toxicity coefficient, synergistic effect and part in this inventive applicant specification.But this wetting powder, water dispersible granules or suspending agent are spray-type, when use, need mix with large water gaging, be finally sprayed to by sprayer on the crop of required processing.But MTI-446 and the composite spray-type of making of desinsection list are used, because drift action can pollute limit, field mulberry tree etc. especially, easily cause silkworm to be poisoned to death; Because medicament is attached to, on cauline leaf, thereby to Chinese cabbage, wild cabbage etc., some does deposits yields poisoning when directly spraying again; Also have this spray-type aspect drug effect, to have short deficiency of lasting period.In addition, use insects such as killing water rice borer, rice fulgorids and mostly perch in the harm of crop bottom, be difficult to be sprayed onto position while spraying, mostly perch at crop number meter high top insects such as killing sugarcane aphid and use, apparatus is difficult to spray.These factors all cause peasant's labour intensity to strengthen, and drug effect is not good on the contrary.Moreover short owing to spraying the lasting period, often need to spray several times medicine, production cost increases.
The formulations of pesticide of having known at present have wetting powder, such as microcapsule formulations of water dispersible granules, suspending agent, missible oil, pulvis, aqua, aqueous emulsion, controlled release form, or as dry spreadable or sow granule etc.The selection of type of dosage form is subject to the impact of application method.The type of dosage form of any appointment and the mode of action all may affect its activity and selectivity.The most preferred dosage form of any specific selectivity Recompounded pesticide will depend on characteristic and any pest that other will be controlled of application method and plant.
Being mixed with granule is also that important commercial product is selected at pesticide industry, uses simply because they have, for example, can or use mechanical spreading method with hand, is that reality practical and that save labour is selected.After spreading fertilizer over the fields, general granule just kills as soil insects such as cutworm, mole cricket or grubs by the mode of tagging.And the present invention attempts to see through the new mechanism of action of granule utilization and reaches the ground insect object that sprays formulation and equally kill damage to crops, improve relevant effect simultaneously.Through retrieval, do not find so far the relevant report of the composite granulation agent of MTI-446 and desinsection list (GR) and application.
Summary of the invention
The object of the invention is to: when spray-type etc. uses in field, have for current MTI-446 and composite the making of desinsection list that the lasting period is short, labour intensity large and use the congruent practical problem of feeling unwell, and then a kind of insecticidal compound agent that contains MTI-446 and desinsection list is provided, preferred manufacture method is further also provided.
The object of the present invention is achieved like this: the insecticidal compound agent that contains MTI-446 and desinsection list, comprise effective active component, carrier and auxiliary agent, effective active composition is MTI-446 and desinsection list, be characterized in that composite rear final preparation is the granule that acts on crop root, wherein the weight ratio of MTI-446 and desinsection list is 1:120～40:1.
Described insecticidal compound agent the present invention containing MTI-446 and desinsection list is preferably: the weight ratio of MTI-446 and desinsection list is 1:80～10:1.
Described insecticidal compound agent the present invention containing MTI-446 and desinsection list is more preferably: the percentage by weight of MTI-446 and desinsection list is 1:30～2:1.
The insecticidal compound agent that the present invention obtains acts on the root system of crop specially, active component conducts to crop complete stool by Root Absorption, thereby kill the ground insect of damage to crops, be fundamentally different from after general granule spreads fertilizer over the fields and just kill as soil insects such as cutworm, mole cricket or grubs by the mode of tagging.
A large amount of toxicity test and field control effectiveness test, result proves that it all has good control efficiency to insects such as rice-stem borer, paddy stem borer, rice leaf roller, rice fulgorid, sugarcane borer, sugarcane aphid, corn borer, vegetables diamond-back moth, aphids.Advantage of the present invention is that the composite granule of making spreads fertilizer over the fields application except energy synergy and expands insecticidal spectrum specifically, key is to find that both Root Absorptions all conduct by force well and upwards, in ratio range of the present invention, its conduction of velocity keeps good concertedness, make active component can be uniformly distributed plant complete stool after Root Absorption, thereby preventive effect is better, the lasting period is longer.
For example with spray the more concrete advantage of formulation geometric ratio and can sum up as follows: 1) can together spread fertilizer over the fields with base manure, saving of work and time, has alleviated the heavy work of spraying; 2) because the slow releasing function of granule can also extend its lasting period greatly, thereby reduced spraying times; 3) can not pollute the mulberry tree on limit, field, safer to people and animals, to natural enemy without killing and wounding (when desinsection single spraying is executed, because drift action can pollute limit, field mulberry tree especially, cause silkworm to be poisoned to death, and adopt granule just not affect because not drifting about); 4) thus avoided when directly spraying that on cauline leaf, some does the poisoning of deposits yields to Chinese cabbage, wild cabbage etc. because medicament is attached to, improved safety in utilization.
The granule that the present invention obtains, both for paddy field, also can be used for nonirrigated farmland.In general when paddy field is used, can or transplant in crop sowing after turning green and together spread fertilizer over the fields with topdressing, and 5 centimeters of water conservations about a week; Blinding after can together spreading manuer in holes with crop seed when nonirrigated farmland is used, also can ridging after crops seedling stage or vegetative period trench digging spreads fertilizer over the fields with topdressing.
The proportioning of effective active composition of the present invention is selected upper except considering that participating in two composite active ingredients its co-toxicity coefficient large (preferably needing to be greater than 120) in certain ratio range has obvious synergistic effect, considers to participate in two composite active ingredients and must possess simultaneously and absorbed by crop root the speed that upwards ability of conduction and Root Absorption upwards conduct simultaneously and need roughly the same such factor also simultaneously especially.
